When you answer "I often don't know who I really am" – which time frame are you thinking of? PD diagnoses require symptoms lasting 2+ years, but common questionnaires specify no time frame at all. We tested whether that matters: 🧵 osf.io/zdbmc with @jzpsych.bsky.social and @uschroeders.bsky.social

Item-level prediction models often outperform scale scores in personality research — usually credited to "nuances" (stable item-specific variance). Our new simulation study shows: measurement non-invariance can produce similar predictive gains.
